CONCEPÇÕES DE ALUNOS DO ENSINO MÉDIO SOBRE TAMANHO DA AMOSTRA E REPRODUTIBILIDADE DE DADOS EXPERIMENTAIS.

This study investigates the perceptions of high school students regarding the concepts of evidence related to the reproducibility of experimental data, also in addition to analyzing the evolution of these concepts over a school year, considering the implementation of a series of diverse practical activities integrated into the school curriculum. In total, 164 first-year high school students fully participated in the research, based on a quantitative approach covering a pre-experimental design with two tests, one at the beginning and another at the end of the school year. In addition to the tests, some students were interviewed. The comparison of the pre- and post-test results indicates, for the group of students surveyed, that there was a certain sophistication in thinking about the constructs researched. However, the analysis of the justifications revealed that a large portion of the participants did not understand the real reasons of the importance of working with a larger number of measurements properly. Based on the results, educational implications are discussed, and new research questions are proposed. [ABSTRACT FROM AUTHOR]
